Water 7, the iconic city from the One Piece series, is primarily based on Italy.
The architectural and geographical design of Water 7 draws significant inspiration from Italy, particularly the city of Venice. This resemblance is evident in its unique landscape, characterized by numerous canals that serve as primary thoroughfares, much like those found in the real-world Italian city. People in Water 7 frequently travel by water, using these canals as their main routes.
Furthermore, Water 7 mirrors Venice's distinct characteristic of being gradually sinking. In both cities, the lower floors of many old buildings are now underwater, a phenomenon that has profoundly shaped their respective appearances and daily life. This striking similarity in its environment and infrastructure establishes a clear connection to the famous Italian "Floating City."
